The historic city of Prague, the capital of the Czech Republic, is home to the RockOpera Theater, a unique spot that has recently been fitted out with D.A.S. Audio professional sound systems. This amphitheater-shaped venue was specifically designed with rock and metal concerts in mind, but is also used for a range of other events that run from plays to fire and acrobatic shows.

The theater owners contracted the Czech company TSI to design and install the sound system. The TSI sound team worked hand-in-hand with Eva Argandoña from D.A.S. Audio’s Sound Projects Department, to carry out the acoustic and auralization simulations used to help select the ideal sound solution. After studying the particular requirements of the venue, particularly the need for vertical coverage, the sound team opted to install line array systems from D.A.S. Audio’s Convert Series.

A total of 13 powered D.A.S. Convert 12A curved source arrays were deployed in three vertical formations on the left, center and right: five units each were flown on the right and three units were flown in the center. The rigging system can be used to form vertical curved source arrays for 15º vertical dispersion, making the Convert 12As the ideal solution for venues with steep stands like Prague’s RockOpera Theater.

The TSI sound team decided to roll out 4 D.A.S. Avant 118A systems to handle the low frequencies and flood the theater with bass. These powered subwoofers come equipped with an 18LX long excursion bass loudspeaker that is both compact and powerful and were ground stacked along the stage.

Four powered units from the new D.A.S. Artec 500 series were also installed, specifically the Artec 508A, a model that features an 8-inch speaker. These systems handled the sound for the upper rows of the steepest stands, specifically enhancing speech intelligibility in these top rows that, because they are so high up, fall under an “acoustic shadow”. The system was rounded out with a D.A.S. Audio DSP-4080 audio processor. These compact 4-input / 8-output systems, ideal for installs, administrate and control the entire professional D.A.S. Audio sound system.

T SERVIS sound technician Ivo Horyna commented about this installation: “Rock Opera´s room is not very wide but very high and we need a system with wider dispersion. The powered D.A.S. Convert 12A curved source arrays are perfect for the job. The 4 Avant 118A Subs are surprisingly enough to provide bass spectrum for the house loud rock band.“
